Formula:
The general formula for beam deflection (δ) varies based on beam type, support conditions, and load type. Key variables include:
- δ: Beam Deflection (m)
- P: Point Load (N)
- w: Uniformly Distributed Load (N/m)
- L: Beam Length (m)
- E: Modulus of Elasticity (Pa)
- I: Moment of Inertia (m4)
For a Simply Supported Beam with a Point Load at its Center, a common formula is:
δ = (P × L3) / (48 × E × I)
